TableStore

Struct TableStore 

Source
pub struct TableStore { /* private fields */ }
Expand description

表快照库:表名 → 当前代 Arc<TableData>

  • 读(调用者取数):snapshot() 短读锁 clone 一个 Arc——O(1),无数据复制; 之后完全无锁读该代。
  • 写(刷新换代):tick 在锁外整建新 TableDatainsert() 只在写锁内做一次 O(1) 的 Arc 指针替换——读者不被重活阻塞,永不读到半代数据。

Implementations§

Source§

impl TableStore

Source

pub fn snapshot(&self, name: &str) -> Option<Arc<TableData>>

取某表当前代快照(None = 尚未有任何一代装载/刷新成功)。

Source

pub fn insert(&self, data: Arc<TableData>)

换入新一代(按 data.name 覆盖当前代)。调用方负责在锁外整建完成。
